I have the sample of softkeyboard. When I install it on a android 2.x, it has the following non-fullscreen view:
But when I install it on tablet 10in it gets whole of the screen like this:
How can I change the sample to have a non-fullscreen custom keyboard on tablet pcs like this image (default keyboard of tablet)?
The following code in InputMethodService solved my problem:
#Override
public boolean onEvaluateFullscreenMode() {
return false;
}
overide the following two methods from InputmethodService as bellow, this works always
#Override
public void onUpdateExtractingVisibility(EditorInfo ei) {
// TODO Auto-generated method stub
setExtractViewShown(false);
}
#Override
public boolean onEvaluateFullscreenMode() {
return false;
}
This worked for me :) and if you want to show keyboard in fullscreen mode always then change both false to true.

I've been developing with codenameone for over a year, and I never ran into this problem before, I feel like I'm losing my mind. I just redesigned one part of an app I'm working on, and now the ActionListeners aren't firing. I'm attaching them to a Button and a SpanButton in the code:
ActionListener goToDoc = new ActionListener() {
String mDocId = docId;
#Override
public void actionPerformed(ActionEvent evt) {
mStateMachine.currentExpertId = mDocId;
mStateMachine.showForm("DoctorDetails", null);
}
};
name.addActionListener(goToDoc);
Util.downloadImageToStorage(mStateMachine.URL_PREFIX+"images/doctors/"+(String)value.get("doc_pic"),
"doc_post_pic_"+(String)value.get("doc_id")+".png", new Callback<Image>() {
#Override
public void onSucess(Image img) {
pic.setIcon(img.scaledWidth(mStateMachine.getProportionalWidth(.23)));
StateMachine.applyGreenBorder(pic);
pic.addActionListener(goToDoc);
pic.getParent().revalidate();
}
#Override
public void onError(Object sender, Throwable err, int errorCode, String errorMessage) {
System.out.println("Unable to download expert profile picture");
}
});
When I debug the code, the components do show that the ActionListener is attached, but the actionPerformed method is never reached, no matter how many times I click on the buttons. I experience this problem both on the simulator and on an Android device. I have yet to test on an iPhone.
Did you set a parent to be a lead component or focusable?
The reason the click event wasn't firing was because the Components weren't enabled, possibly a bug in the BUI Builder. After checking off the 'Enabled' and 'Focusable' checkboxes in the GUI Builder, and seeing they were unchecked every time I went back to that form, I just used component.setFocusable(true) and component.setEnabled(true) in the code, and it worked fine after that.
The example on https://developers.google.com/cast/cast_2nd-screen_app_tutorial shows a onDestroy method which calls unregisterMediaRouteProvider. This causes the MediaRouter.Callback.onRouteUnselected method to get called which in turn ends the session. This leads to the app getting disconnected from the chromecast device and the MediaRouteButton stops being blue. Below is the onDestroy method from the example:
#Override
protected void onDestroy() {
MediaRouteHelper.unregisterMediaRouteProvider(mCastContext);
mCastContext.dispose();
super.onDestroy();
}
So my question is, what is the proper way to handle screen rotation when using the chromecast device from an app?
You can try using isFinishing() method of Activity to figure out if onDestroy is called due to application really "finishing" or is called for other reasons. Another option is to handle orientation change yourself.
You can see the guidelines for handling setup/destruction of the Chromecast (such as when orientation change is happening) on https://developers.google.com/cast/docs/android_sender
The relevant sections of code are the following ones:
#Override
protected void onResume() {
super.onResume();
mMediaRouter.addCallback(mMediaRouteSelector, mMediaRouterCallback,
MediaRouter.CALLBACK_FLAG_REQUEST_DISCOVERY);
}
#Override
protected void onPause() {
if (isFinishing()) {
mMediaRouter.removeCallback(mMediaRouterCallback);
}
super.onPause();
}
And also the following code:
#Override
protected void onStart() {
super.onStart();
mMediaRouter.addCallback(mMediaRouteSelector, mMediaRouterCallback,
MediaRouter.CALLBACK_FLAG_REQUEST_DISCOVERY);
}
#Override
protected void onStop() {
mMediaRouter.removeCallback(mMediaRouterCallback);
super.onStop();
}
It is also a good idea to have a boolean value in your program, for instance "wasLaunched" or "isConnected" to keep track of whether the connection to the chromecast is active or not. I use this variable in my code to check if I can send messages to the receiver or not. Then simply remember to save this variable and restore it when there is an orientation change on the device. This works for me in my chromecast enabled app. The code for saving/restoring my variable, so it survices orientation change is shown below:
protected void onSaveInstanceState(Bundle bundle) {
if (bundle!=null)
{
bundle.putBoolean("wasLaunched", wasLaunched);
}
super.onSaveInstanceState(bundle);
}
protected void onRestoreInstanceState(Bundle savedInstanceState) {
if (savedInstanceState!=null)
{
wasLaunched = savedInstanceState.getBoolean("wasLaunched");
}
super.onRestoreInstanceState(savedInstanceState);
};
Of course you can also put other stuff in your bundle that needs to survive an orientation change. I am not using the onDestroy override you describe there, nor is it mentioned in the google documentation I link to. But I use the teardown() method described in that document I link to for cleaning up, but this only happens when I close the connection, because I dont want to close the connection to the chromecast upon orientation change.
I'm building my app using the Nokia SDK 1.0 for the Asha 501
What I want to know, is how to capture events by pressing a TextArea. I'm porting an app from the S40 and using the code below, the TextArea doesn't capture the events
TextArea itemText = new TextArea("Hello I'm a TextArea", 2, 22) {
public void pointerPressed(int x, int y) {
System.out.println("PRESSED");
}
public void pointerReleased(int x, int y) {
System.out.println("HI!");
}
};
itemText.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent ae) {
System.out.println("HI");
}
});
itemText.setEditable(false);
itemText.setFocusable(false);
itemText.getStyle().setBorder(null);
itemText.getStyle().setFgColor(Constants.Style.Color.GREY_DATE);
itemText.getStyle().setBgTransparency(Constants.Style.TRANSPARENT);
itemText.getStyle().setFont(Font.createSystemFont(Font.FACE_SYSTEM, Font.STYLE_PLAIN, Font.SIZE_SMALL));
EDIT
Someone in the Nokia Forum, tells me to delete the itemText.setFocusable(false); line, but it doesn't work.
I've finally found what is the problem, I don't know the reason why but that's it.
Removing this line
itemText.setEditable(false);
the TextArea catches the events.
I don't find the reason that in Nokia SDK 2.0 this code is working and why here is not. Ande there is another fact. I set the TextAreato editable, and it is not editable o_O
I am making an application using LWUIT.
There is a form
There is a list embedded on the form.
The list has 5 elements.
Initially, when I first load the app, if I choose the 1st element, 2nd gets chosen; when I choose the second the 3rd gets chose and and so on (Weird!)
I am not able to click any button on the screen either
next what I do is, shift to a different from using arrow keys (of the keyboard... I am running the app on a simulator btw)
Then I come back to the first form and now everything works as expected(no weird behaviour).
What could be the issue?
I am using Sun Java Micro Edition SDK 3.0 (default touch screen for testing)
My code is:
List dummy = new List();
dummy.addItem("wewerwer");
dummy.addItem("wewerdswer");
dummy.addItem("wewqweerwer");
dummy.addItem("dscxwewerwer");
dummy.addItem("jhgwewerwer");
mainListForm.setLayout(new BorderLayout());
mainListForm.addComponent(BorderLayout.CENTER,dummy);
mainListForm.show();
What could possible be going wrong here?
UPDATE 1
I think there is a bug here. I have attached the complete code below along with the screen shot
import javax.microedition.midlet.*;
import com.sun.lwuit.*;
import com.sun.lwuit.events.*;
import com.sun.lwuit.plaf.UIManager;
import com.sun.lwuit.util.Resources;
public class Demo extends MIDlet implements ActionListener {
private Form mForm;
List abc;
public void startApp() {
Display.init(this);
try {
Resources r = Resources.open("/Test.res");
UIManager.getInstance().setThemeProps(r.getTheme(
r.getThemeResourceNames()[0])
);
} catch (Exception e){
System.out.println(e.toString());
}
if (mForm == null) {
Button click = new Button("Press me!");
click.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent ae) {
System.out.println("I have been pressed");
}
});
abc = new List();
abc.addItem("Str1");
abc.addItem("Str2");
abc.addItem("Str3");
abc.addItem("Str4");
abc.addItem("Str5");
abc.addItem("Str6");
Form f = new Form("Hello, LWUIT!");
abc.addActionListener(this);
f.addComponent(abc);
Command exitCommand = new Command("Exit");
f.addCommand(exitCommand);
f.addCommandListener(this);
f.addComponent(click);
f.show();
}
}
public void pauseApp() {
}
public void destroyApp(boolean unconditional) {
}
public void actionPerformed(ActionEvent ae) {
System.out.println(abc.getSelectedIndex());
}
}
So now when I click on 'Str1' of the list Str2 gets selected and so on.
IDE: Netbeans
Emulator: Default Touch screen phone
On the action event set the list to active again after the event by invoking setHandlesInput(true)
OK....so this is how you resolve it.
After the form is displayed remove the list from the form and again add it to the form and then repaint the form.
Earlier Code
1) form.addComponenet(BorderLayout.center,list);
2) form.show();
Word Around for the problem
1)form.addComponenet(BorderLayout.center,list);
2)form.show();
3)form.setScrollable(false);
I know its kind of strange, but this way the list index selection works smooth for touch screen phones.
I am working my way through the NeHe OpenGL examples, using the LWJGL for the OpenGL binding inside an Eclipse RCP application.
My OpenGL graphics are displayed inside the RCP canvas, not in a separate window.
Lesson 07 shows how to use the keyboard. If I try to do a:
Keyboard.create();
I get an error that the (OpenGL) "Display" has not been created.
If I create an OpenGL "Display" with org.lwjgl.opengl.Display.create(), then I get a new Window.
So how do I access the Keyboard without creating a new Window?
You cannot use the Keyboard without a Display, because of how LWJGL works behind the scenes. The best way is to just use AWT events. You can write your own input class, that could go something like this.
public class Input implements KeyListener {
private boolean aDown; //is the A key down?
//Ect, for all needed keys
public void keyPressed(KeyEvent ke) {
switch (ke.getKeyCode()) {
case KeyEvent.VK_A: aDown = true; break;
//and so on for all other needed keys.
}
}
public void keyReleased(KeyEvent ke) {
switch (ke.getKeyCode()) {
case KeyEvent.VK_A: aDown = false; break;
//and so on for all other needed keys.
}
}
public void keyTyped(KeyEvent ke) {} //Do nothing
public void isADown() {return aDown;}
}
